20 Claims.

This invention relates to grain shockers particularly adapted for use in connection with ordinary grain binders to receive the sheaves or bundles as they are delivered from the binder, and to arrange the sheaves in shock form to be deposited upon the ground while the binder and shocker are drawn over a field.

The principal object of the invention is to provide a device of this character which is positive in operation and capable of setting upright shocks which are stable and well adapted in shedding the elements.

Other objects of the invention are to provide a shocker adapted for automatic operation; to provide a shocker that is of relatively simple construction compared to the work accomplished; to provide a shocker with a form on which the bundles are successively packed when delivered thereto by an automatically operated carrier operating in synchronism with the binder mechanism; and to provide means for automatically stripping the shock from the form and depositing the shock on the ground.

In accomplishing these and other objects of the invention, as hereinafter pointed out, I have provided improved details of structure, the preferred forms of which are illustrated in the accompanying drawings, wherein:

Referring more in detail to the drawings:

l designates a standard grain binder having a frame 2 supported on a main ground wheel 3, and adapted for carrying a bundle tying and delivery mechanism generally indicated 4. The

bundles when formed and tied are delivered therefrom upon release of a trip hook 5 and actuated through a pitman 6 that is connected by a wrist pin 1 with an actuating gear 8. In the binder illustrated, the various mechanisms are driven from th main traction wheel through a counter-shaft as in conventional practice, or from the power take-off 8' from the tractor which pulls the binder. The binder specifically forms no part of the present invention, but is illustrated to give better understanding of the shocker, and the parts of the binder mentioned relate to operation of the shocker embodying the present invention.

The shocker is generally indicated 9, and includes a frame NJ having a main transverse sill II to which are secured spaced longitudinal sills I2 and I3 connected at their forward ends by a transverse member I4. The outer side of the frame, which includes the longitudinal sill I3, carries an adjustable spindle mounting a supporting wheel I5. The main transverse sill is connected by an angularly diverging draft arm IS with the draft tongue of the binder. The inner end of the main sill has an extension I1 and terminates in a hook I8 engaged in a bracket I9 on the side rail of the binder frame 2, at a point below the bundle delivery mechanism 4.

The sills I2 and I3 extend rearwardly from the main sill and are braced therefrom by diagonals 28 and 2I to form the main supporting structure for the shock forming mechanism, later described. The forward end of the sill I2 cooperates with a longitudinal member 22, which connects the main sill with the transverse member I4, to mount the shocker actuating and timing mechanism. The rear ends of the sills I2 and I3 mount rear legs 23 and 24 of a tower-like frame 25, which also includes forward legs 25 and 21 connected with the forward ends of the longitudinal sills. The front and rear legs are connected by spaced horizontal members 28 and 29 carrying a substantially circular platform 38, having a central opening SI for a purpose later described. The forward ends of the horizontal members 28 and 29 are braced from the front legs by suitable gusset plates 32 and 33. The gusset plates extend above the horizontal members and connect with spaced upper extensions 34 and 35 of the legs, as best shown in Fig. 2. Cooperating with the leg 23 is a shorter leg 36 spaced forwardly therefrom and connected at its lower end to the 1ongitudinal member I2, and at its upper end by a gusset plate 31 (Fig. 2) with the leg 23.

The legs 36 and 23 carry a longitudinal member 38 that is supported below the upper member 29. Attached to the rear leg 24, at the opposite side of the machine, is a similar horizontal member 39 having its forward end supported by a brace leg 48. The lower end of the brace leg 48 is carried on an arcuate rail 4|, having one end attached to the main transverse sill and its rear end supported on the rear end of the outer longitudina1 sill I 3, as best shown in Figs, 3, 4,9 and 10. The leg 48 is of sufficient length to connect with the other of the upper horizontal members 28, as clearly shown in Fig. 2.

The legs 23 and 48 cooperate with the arcuateshaped member 4! to carry an arcuate-shaped, inwardly flaring plate 42, which forms a guard contacting the lower ends of the bundles that are deposited on the shocker form, later described. These legs are further connected by an arcuate rail 43 located at the upper edge of the guard, and an upwardly spaced, arcuate rail 44. The leg members 23, 24, 36 and 48 thus converge upwardly to intersect with an extended axis of the opening 3| in the platform 39.

Carried by the lower and shorter longitudinal members 38 and 39 is a collar 45, having its upper end supported by the platform 38. The forward le s 26 and 21 are connected by a cross tie 46, and the leg 21 is connected with the front transverse member I4 by a brace 41. Slidable in the collar 45 is a shock forming mechanism 48, including a cylindrical body 49, best illustrated in Figs. 15, 16 and 17. The upper end of the tubular body carries a laterally extending annular flange 58, which normally rests upon an oscillatory ring 5| Journalled to oscillate about the tubular body and having diametrically arranged arms 52 and 53.

The arms 52 carries a pivoted pawl 54, engaging with ratchet teeth 55 formed in the periphery of the flange 58. The other arm 53 is connected by a link 56 with an arm 51, carried on the upper end of a shaft 58 which is journalled in a hearing 59 carried upon a bar 69, the shaft 58 being operated in a manner later described. The tubular body depends through the collar 45 and has its lower end closed by an inset head 6|, between which a circular series of depending flexible arms 62 are suspended from rivets 83, passing through a flange B4 on the head and through the lower portion of the tubular body, as clearly shown in Figs. 16 and 17.

Reciprocably mounted in a polygona1-shaped opening is a reciprocatory shaft 86 of similar cross-section. The upper end of the shaft projects through an opening 61 in an inset head or partition 68 near the upper end of the tubular body. The projecting upper end of the shaft terminates in a reduced threaded shank 69 on which a yoke 18 is swivelly mounted. The yoke 18 is pivotally connected by a pin 1I carried at one end of a rocker arm 12. The rocker arm 12 is pivotally mounted on a cross-pin 13 carried at the outer ends of spaced links 14 and 15. The lower ends of the links are connected by a similar cross-pin 18 with links 11 pivoted to the upper portion of the gusset plates 33 on a crosspin 18. The rear arm of the rocker arm 12 is connected by a cross-pin 19 with links 89 and BI, having their lower ends pivotally connected with a cross-pin 82 carried by the projecting upper ends 34 and 35 of the forward legs 26 and 21. Pivoted on the cross-pin 82, between the links, is a similar rocking lever 83, having its forward end projecting between the links 14 and 15 and connected therewith by a cross-pin 84 at a point spaced below the cross-pin 13 at a distance equal to the pivotal spacing between the pivots of the links 88 and 8|. Pivoted to the opposite end of the rocking lever, by a yoke 85, is a pitman 89 adjustably connected, as at 81, with a crank-arm 88, later described.

The tubular body 49 and mechanism carried thereby, as well as the rocking levers, are pivotally balanced by means of a spring 99, having one end fixed to a stirrup 9| carried by the rocking lever 83 and its opposite end fixed to the cross tie 46 by an eye-bolt 92, as shown in Fig. 2.

Projecting from the lower end of the shaft 86 is a reduced extension 93 forming a shoulder 94 with the polygonal portion of the shaft. Abutting against the shoulder 94 is a collar 95, spaced from a similar collar 93 by a sleeve 91. The collar 98- is retainingly engaged with the lower end of the sleeve 91 by a sleeve 98, spacing a third collar 99 which is retained on the reduced extension by a nut I99, as clearly shown in Figs. 16 and 17. The collars 95 and 96 have a plurality of radially extending ears I9I and I82 respectively, to which are pivoted arms I83 and I84, having single and double tines or prongs I85 and I88 respectively, and which project through pocket-like openings I81 and I98 of the flexible arms 62, and extensions I89 attached to the lower ends thereof. The extensions I99 have inwardly directed ears II8 that are connected by links III with ears II2 on the collar 99. The shaft 66 has reciprocal movement within the cylindrical body of the shock former, limited by a bumper II3 on the downstroke, and limited on the upstroke by the collar 95, so that the tines I95 and I 99 are projected through and retracted from the pocket-like openings incidental to spreading of the flexible arms 52 by the links III as clearly shown in Figs. 16 and 17.

With this arrangement the reciprocatory shaft 66 has independent movement relatively to the tubular body 45 at the beginning of the upstroke or until the collar 95 engages the head 6|. The shaft and tubular body are then raised together during the remainder of the upstroke. On the downstroke it is desirable that the tubular body and shaft move together until the flange 50 seats on the upper end of the collar 45 and unless there is a direct connection between the shaft and tubular body, the tubular body will tend to lag. In order to overcome this difficulty, I have provided a latch, best illustrated in Figs. 18 and 19, whereby the tubular body is connected with the shaft during the initial upward movement of the tubular body. Therefore on the downstroke the tubular body will move at the same speed as the shaft, but just before the flange 55 reaches the upper end of the collar 45 the latch will be disengaged. The latch includes a plate 3 slidably fixed on the partition 58 and having an elongated opening 51 therein for passing the shaft. Carried by the plate 38' is a tongue I38 adapted to engage in a notch 61" in the side of the shaft, as clearly shown in Figs. 18 and 19. The plate 68' is urged toward latching position by a spring 49 but is retained out of latching engagement by means of a lever 49". The lever 43 is pivotally mounted, as at 45, to the inner wall of the tubular body and has its upper end acting through a slot 45" so that when the tube begins to move through the collar 45 on the upstroke, that end of the lever will pass through the slot and allow the spring 45 to move the plate 68 into latching engagement with the shaft. Therefore directly at the beginning of the downstroke of the shaft, the tubular body will move therewith until the projecting portion of the lever is cammed inwardly by engagement with the upper end of the collar 45 so that the opposite end of the lever effects retraction of the tongue 68 from engagement with the notch 61''. The tubular body then comes to rest with the flange 55 thereof seated on the upper end of the collar 45 and the shaft continues its downward movement expanding the arms on which the sheaves are empaled, as later described.

Mounted on the opposite diametrical sides of the collar 45 are shock absorbers I I I of anysuitable character for checking downstroke of the shock former.

The mechanism just described forms the core of the shock, and the outer portion is formed by the arcuate guard plate 42 cooperating with the rail 44 and gates H and H5 normally closing the space between the rear legs 23 and 24. The gates H5 and H5 are of substantially the same construction and include rock-shafts II I. having their lower ends pivoted in hearings IIB and their upper ends rotatably mouned in universal bearings I I9, carried by plungers I25 (Fig. 4) slidable in tubular arms I2! supported by a lower plate I22 carrying the collar 55 (Fig. 1), the plunger being retractible by coil springs I23 engaging against a head I24 of the plunger, and against collars I25 anchored in the arms I2I by set-screws I25.

The lower portions IE'I of the rock-shafts II'I converge upwardly in accordance With'thB conical contour to be imparted to the shock. but the upper portions I28 extend substantially perpendicular when the gates are in closed position as shown in Fig. 1. Carried by the portions I21 of the rock-shafts II! are arcuate arms I29 which cooperate with the rail 43 and guard plate M to form a substantially circular band about the shock, with the exception of the space between the legs 36 and 40.

- When the gates are opened, and the shock carrier raised to deposit a shock, the shockis pressed by a substantially arcuate-shaped arm I30 carried by the rock-shaft ill of the gate I I 6, to move in front of the shock when the gates are opened, as later described. The arm I30 is pivoted on the rock-shaft and is actuated upon closing of the gates by a link I33 fixed to the arm I34 of the rock-shaft I35, having its lower end pivoted in the rail 43 and its upper end'in a bracket I36 projecting from the rail 54, the shaft being oscillated incidental to opening and closing of the gate by means of a link I31 connecting an arm I38 On the shaft I35 with an arm I39 onthe rock-shaft III of the gate I It. In order that the arm I30 may be yieldably retained in position, it is connected by a link I45 with an arm of a bell-crank ItI, which is pivoted on the shaft I35 and has its other arm connected by a spring I42 with the leg 24 (Fig. 9).

The upper ends of the rock-shafts III carry crank-arms I43 and I44 that are connected by links I45 and M6 with arms I4'I- and I45 on a rock-shaft I59 having its ends pivotally mounted in the forward ends of the short longitudinal members 33 and 39. Depending from the shaft I49 is an arm I55 (Fig. 3). The arm I50 is connected by a link I 5! with the cross-pin 'IiLpreviously mentioned, so that when the rocking levers are actuated to raise and lower the tubular body of the shock former, the gates are simultaneously actuated to permit deposit of a shock under the pressing influence of the arm I30.

The sheaves are received by a sheaf carrier generally designated I52 and including hinged cradle parts which are normally supported in open position parallel with the bundle or sheaf discharge of the binder. The sheaf carrier is adapted to swing and simultaneously rotate to a vertical position so that sheaves carried thereby may be removed from the carrier and deposited on the tines by a packer generally designated I53. The packer I53 comprises a crank-shaft I54 inclined upwardly toward the vertical axis of the shock former and has its lower end rotatably mounted in a bearing I55 of a gearing housing I55, later described. The upper end of the crankshaft connects through a universal joint I51 with the shaft 58 previously described, the universal joint connection being rotatably supported by an arm I53 projecting from the plate I22 (Fig. 2). The intermediate portion of the crank-shaft is offset to provide a crank I59 adapted to gyrate in a circular path when the crank-shaft is rotated as later described. Loosely mounted on the crank-shaft is a series of spaced packer arms I65, having forked terminals IEI and IE2 adapted to straddle the uprighted bundle and to push the bundle from the carrier onto the tines of the shock former. The packer arms have tail portions I 63 connected by links I54 with a fixed part of the frame, so that when the crank is rotated the forked arms of the packer oscillate to and from engaging position with an uprighted bundle.

, The sheaf carrier I52 is movably mounted on a support I65 forming a part of the gear housing 15:; Figs. 7. 8, 10 and 11). The support I55 has a head I55, having an axial bore IB'I extending transversely of the direction of travel of the machine and slightly inclined upwardly toward the binder side of the machine, as clearly shown in Fig. 11. Rotatably mounted in the bore I61 is a shaft I68 carrying, at one end, a bracket I69, and at its other end a lever arm I adapted to actuate the piston (not shown) of a check or dash-pot Ill. The bracket I69 includes a sleeve portion I12 fixed rigidly to the shaft I61 and which has a T-shaped head I13, having a bore in which is oscillatably mounted a shaft I14 which extends in a substantially fore and aft direction when the carrier is in receiving relation with the binder, and which is adapted to swing to a substantially vertical position when the carrier is moved to deposit a sheaf on the shock former. Fixed to the end of the shaft is the arm I15 of a yok I16. The branches I11 and I18 oscillatably journal a shaft I19 on which the sheaf carrier is mounted, as best shown in Figs. 8 and 11.

Carried by the shaft I19, at spaced points along the length thereof, are plate-like brackets I80, terminating at their edges opposite the shaft in socket portions I 8| to mount the shanks I82 of fingers I83, the shanks being adjustably supported in the sockets by set-screws I84 (Fig. 11). The fingers I83 cooperate with each other when the carrier is in receiving relation with the binder to form a substantially trough-like basket into which a sheaf is deposited. Oscillatably journalled in the plate-like brackets I80 are spaced, parallel shafts I85 and I86, having laterally extending arms I81 and I88 pivotally interconnected by a link I89. longer arm I00, having pivotal connection I9I with a latch-like control lever I92, later described. The shaft I86 mounts a plurality of fingers I93, curved oppositely to the fingers I83 and adapted to cooperate therewith in gripping a sheaf when it is to be carried from receiving position to a position where it is deposited upon the shock former. The fingers I93 are formed of spring-like material and their anchoring ends terminate in coils I94 sleeved over the shaft I86 and have their ends anchored to the plate-like brackets I80. The shaft I86 has an arm I95 for each finger I 93, and these arms are fixed to the shaft so that they rotate therewith. The ends of the arms I95 have sleeve-like terminals I96 through which the fingers I93 are respectively extended. The fingers I93 are therefore connected with the arms I95, and are adapted to rotate with the shaft when the respective fingers are moved to open position for receiving a sheaf,

as shown in Fig. 11. This movement of the fingers winds the coils I94 about the shaft I86 so that the stored up tension returns the fingers into gripping relation with the shaft when the control arm I90 is tripped through the latch arm I92, as now to be described.

Also forming an integral part of the bracket I69 are oppositely directed arms I91 and I98, carrying laterally extending studs I 99 and 200 respectively. The control lever I92 has a slot I provided with offset portions 202 and 203 forming a latch shoulder 204 therebetween adapted to engage the stud 200 which holds the fingers of the carrier in open position against action of the spring-like coils I94, as shown in Fig. 11. The control lever I92 is normally urged into position so that the latch shoulder thereof is moved into engagement with the stud 200. This is effected by a roller 205 engaging the edge of the control lever and having pressure exerted there- The shaft I85 also carries a I against by a spring 206 sleeved over a shank 201 that is slidably mounted in an extension 208 of the arm I98.

Pivoted on the shaft I19 is a control link 209 having a slot 2| 0 in which the stud I99 is engaged. When the latch shoulder is engaged with the stud 200, the link 209 is in a position so that the stud I99 engages the rear end of the slot 2| 0 (Fig. 11). As previously stated, the carrier is adapted to simultaneously swing from a horizontal position parallel with the sheaf discharge of the binder through an arc to a substantially vertical position where the sheaf is removed and deposited on the tines of the shock former by the packer I53. This movement is effected by means of a rocker arm 2I I, keyed, as at 2I2, with the upper end of a shaft 2| 3 which is rotatably mounted in a sleeve-like bracket 2I4 carried by the gear housing I56 adjacent the bracket I65. One terminal 2I5 of the rocker arm 2II terminates in a ball 2| 6, engaged in a ball socket 2I1 of a rod 2I8 having a ball and socket connection 2I9 with the lower arm I91, previously described. The other terminal 220 is connected by a ball and socket joint 22I with a link 222, which in turn is connected with an ear 223 on the shaft I19 by a clevis 224. It is thus obvious that when the shaft is turned to move the rocker arm in the direction of the arrow, as at A (Fig. 11), the rod 2I8 exerts a pushing force against the arm I91 that causes the bracket I69 to rotate with its carrying shaft I68 in the direction of the arrow as at B (Fig. 11). Simultaneously the link 222 exerts a pulling force in the direction of the arrow C, so that the arm I15 swings in the direction of the arrow D. Consequently, the bundle carrier will move from receiving position, as shown in Fig. 8, to a discharge position, as shown in Figs. 9 and 10.

All of the mechanisms previously described are powered from the binder and auxiliary engine operating binder mechanism, or from a power take-off of a tractor pulling the binder, as previously mentioned. In the illustrated instance the power is taken from a power shaft of the binder and under control of the sheaf delivery mechanism, now to be described.

Connected with a driven shaft 225 of the binder, by means of a universal joint 225, is a telescoping shaft 221, which in turn is connected by a universal joint 228 with a shaft 229, Figs. 9 and 11. The shaft 229 is rotatably supported in a sleeve-like bearing 230 carried by the gear housing adjacent the sill I2. The shaft projects into the gear housing and carries a helical gear 23I, meshing with a helical gear 232 rotatably mounted on a counter-shaft 233, which is rotatably mounted at the ends thereof in suitable bearings 234 and 235. The counter-shaft 233 extends transversely of the machine, and has a bevelled gear 236 meshing with a bevelled gear 231 on the shaft I 54, which shaft operates the packer previously described. Fixed in driving relation with the gear 232 is a sprocket 238 for driving a sprocket 239 rotatably mounted on a crank-shaft 240. The crank-shaft 240 is rotatably journalled in bearings 24! and 242 and carries the crank 88, previously described. The sprockets 238 and 239 are interconnected by a driving chain 243, as best shown in Fig. 11. The gear 232 is connected in driving relation with the shaft 233 by means of a trip clutch 244, having a rotary member 245 connected with the gear, and a rotary member 246 fixed to the shaft shaped end on the lever.

233, and which is adapted to be drivingly interconnected with the member 245 uponrelease of a trip lever 241, which is engageable by a stop lug 246 on the driven element 246.

The trip lever 241 is in the form of a bellcrank, best shown in Fig. 12, and is pivotally mounted on a stud 249 carried by part of the gear case I56. The bell-crank has one terminal 256 adapted to stoppingly engage the stop lug 248, and an oppositely arranged terminal 25I adapted to engage a diametrically arranged stop lug 252 on the driven element 253 of a trip clutch 254, which is mounted on the shaft 246. The driving element 255 of the clutch is connected in driving relation with the sprocket 239. The bell-crank also includes an arm 256, connected by a link 251 with an arm 256 on a shaft 259. The driven element 253 of the clutch is also controlled by a bell-crank lever 266 that is pivotally mounted, as at 26I, on the leg 21, and has an arm 262 engaged with a lug 263 on the driven member 253, and an arm 264 connected by a link 265 with an arm 266 on an actuating shaft 261. The driven element of the trip clutch 254 is also controlled by a lever 268 pivoted, as at 266, on a brace 216 path of the lug 263 by asp ring 212 that is sleeved on the shaft 246 and pressed against a yoke- The lever 268 has a depending arm 268' provided with a springpressed head 268" for a purpose later described. A lever 213 is fixed to the shaft 246 and has ends 214 adapted to engage a pivoted pawl- 215 for preventing retractive rotation of the shaft (Fig. 7

The shaft 256 is connected with a telescoping shaft 216 by a universal joint 211.' The other end of the telescoping shaft is connected by a universal joint 216 with a shaft 219, mounted on the frame of the binder and having an arm 280 that is connected by a trip lever 28I through a link 282. The trip lever 28I is pivotally mounted, as at 283 (Fig. 6), and has the free end 284 adapted to be engaged by the projecting end of the wrist pin 1, previously mentioned. It is thus obvious that when the gear 8 is making a revolution to release a sheaf from the binder into the carrier, the wrist pin engages the end 284 of the lever 28I to actuate the shaft 259 and effect movement of the bell-crank lever 241, so that the terminals 256 and 25I are moved out of stop engagement with the lugs of the respective clutches. Also connected with the arm 258 is a rod 285 connected with a lever 286 pivotally mounted, as at 281, on the leg 21 Fig. '1). The free end of the lever 286 carries a roller 288 adapted to engage the tail portion 289 of a lever 296 that is pivotally mounted, as at 29I, in such a position that the free end 292 thereof engages under the control lever I92, thereby raising the control lever on its pivotal connection I9I'to effect release of the shoulder 264 from engagement with the stud 266, whereupon the stored up tension in the coils I94 snaps the fingers I93 into gripping engagement with a sheaf deposited v on the fingers I83, as later described. When the bell-crank lever 241 is shifted out of position to disengage the lug of the trip clutch 244, the other trip clutch will not be effective since the bell-crank lever 266 maintains stopped engagement with the lug 263, as shown in Fig. '1. Therefore, only the parts actuated by the shaft 233 will be operated, that is, the sheaf carrier will be moved from a receiving relation with the binder to its position adjacent the shock former, the packer moved to disengage the sheaf, the carrier returned to receiving relation with the binder, and the shock forming tube rotated one step in its supporting collar.

The tube of the shock former does not reciprocate to release a shock until the shock is completely formed and the first deposited sheaf reaches a position to actuate a finger 294 that is yieldably mounted on a rod 295 extending alongside the leg 23 and having connection with a rod 266 which has a crank 291 on its lower end.

' Y The crank 291 is connected by a link 298 with a rod 239, reciprocably mounted alongside of the sill I2 and which connects with a lever arm 366 on the shaft 261 (Fig. 2). The arm 366 and rod connected therewith are normally retained in retracted position by a spring 36I fixed to the arm and having its opposite end anchored to the sill I2, as shown in Fig. 2. Therefore when the shock engages the finger, the shaft 261 is actuated to move the bell-crank lever 266 so that the arm 262 thereof is disengaged from the lug 263, whereupon the trip clutch 254 is rendered effective in rotating the crank-shaft 246, whereby the crank 88 is actuated to operate the rock levers 83 and 12 to raise the tube 49 in its supporting collar and effect collapse of the arms 62 with retraction of the tines, so that the formed shock is slipped therefrom and deposited on the field.

Operation of the shaft 246 also effects opening of the gates through the shaft 58, previously described. The shaft 246 is also rendered effective in releasing sheaves deposited from the shock former under control of the operator. This is effected by a hand lever 362 mounted adjacent the operator's seat 363 on the binder (Fig. 6), and which is connected by a link 364 with an arm 365 attached to the end of the rock-shaft 366 journalled on the binder. The shaft 366 is connected by a flexible joint 361 with a telescoping shaft 368, which in turn is connected by a flexible joint 369 with a hookshaped'lever 3 I 6 engaged by the arm 366. Therefore when the lever 362 is rocked and the shafts connected therewith rotated, the hook 3I6 is effective in swinging the arm 366 to accomplish the same result as effected by the yieldable finger 294 which is contacted by a sheaf on the shock former.

Owing to the fact that the trip clutch has two stop lugs, it is necessary to provide means for retaining the bell-crank lever 241 out of position while the lug 263 passes the terminal end 25I thereof. This is effected by providing the bellcrank with a lug 3 that is adapted to be engaged by a cam 3I2 on a crank-arm 3| 3 on the lower end of the shaft 2I3, which arm is connected'by a 'link .3I4 connected with a wrist pin 3I5 mounted on the lower face of the gear 231 Therefore when the gear moves to rotate the shaft I 54, the shaft 2I3 is also operated, and the arm thereof engages the lug to hold the terminal 25I thereof out of the path of travel of the lug 263, as shown in Fig; 12. However, upon return movement of the arm 3 I 3 responsive to continued rotation of the gear 231, the arm moves away from the lug to permit a spring 3I6 to move the bell-crank into position for stoppingly engaging the lug 252.

It is possible when the shock is nearly formed,

for the first shock to have reached the finger 294 before the bundle carrier has finished deposit of a sheaf on the form carrier. In order to prevent actuation of the shock former until the last sheaf has been deposited, the lug 21I on the ment to deposit the sheaf contained therein.

However, when the bundle carrier has functioned and begins its return stroke, an arm 3I1 engages the head 266 on the arm 268, previously mentioned, so that the lever 268 is shifted against action of the spring 212 to retract the lug 21I thereon from contact with the lug 263. This releases the clutch 254 so that the shock former is actuated to deposit the completed shock. The head 268 is carried by a stem 3I8 slidable in a spring housing 3 I 9 fixed to the terminal end 268 of the arm 268. Contained within the housing and sleeved over the stem 3I8 is a coil spring 320, having one end bearing against a collar 32I on the stem and its opposite end against a plug 322 closing the top of the spring housing. Thus when the arm 3I'I is moved in an anti-clockwise direction (Fig. the arm engages an inclined portion 323 of the head 268" to raise the head against action of the spring 320. However, upon passing the arm 3I1, the spring returns the head to normal position so that return movement of the arm engages the head to swing the lever out of clutch stopping position.

In using the shocker, the draft arm i6 is connected with the draft tongue of the binder, and the extension I1 of the main sill II is connected with the bracket I9 which is attached to the binder. The telescoping shafts 216, 308 and 221 are then connected and the machine is ready for operation. As the binder is drawn along the field, the cut grain is delivered to the tying mechanism, formed in sheaves or bundles which are tied and then discharged incidental to actuation of the mechanism 5, in response to rotation of the gear 8. As the gear rotates, the wrist pin 1 engages the free end 284 of the lever 28 I, whereby the lever is momentarily rocked on its pivot 283 to rock the shaft 219 through the link 282 and arm 280 and partially rotating the telescoping shaft 216 and the connected shaft 259 which rocks the arm 258 to swing the lever 286 through the link connection 285. Since the sheaf carrier is normally at rest in open position to receive the discharged sheaf, it is deposited upon the fingers I83 and is now ready to be gripped by the fingers I 93. Movement of the lever 286 causes the roller 288 to engage the tail portion of the lever 290 so that the free end thereof raises the control lever I92 against action of the spring 206, thereby disengaging the stop shoulder 204 with respect to the stud 200. The stored-up action in the springs I94 is then released so that the fingers I93 move to clamping position with respect to the fingers I83 and grip the sheaf. During this movement the control lever I92 shifts so that the stud 200 is positioned in the portion 202 of the slot. Simultaneously the arm I90 has swung to the right, shifting the arms I81 and I88 through their link connection I09 to the positions shown in Fig. 13. Substantially simultaneous with these operations, the arm 258 rocks the bell-crank lever 241 through the link 251, moving the terminals 250 and I thereof out of engagement with the lugs 248 and 252 on the driven members of the trip clutches 244 and 254. However, the bell-crank lever 260 is not operated, and the trip clutch 254 remain stationary. Since the shaft 221 is rotating the shaft 229 and gears HI and 232, the driven element 245 of the trip clutch 244 is being constantly rotated and upon release of the driven element 246, the clutch connection is effected with the shaft 233. Consequently the gear 236 will rotate the gear 231 and operate the link 3M to swing the arm 3I3 and effect oscillation of the shaft 2I3. This movement of the shaft 2I3 in the direction of the arrow A (Fig. 11) causes the arm 2I5 to exert a pushing force on the rod 2I8 so that the bracket I69 is rotated in the direction of the arrow B with the supporting shaft I68 thereof rotating in the bore I61. This movement of the bracket I69 effects movement of the sheaf carrier I52 from a horizontal toward a perpendicular position. Simultaneously with these movements the other terminal 220 of the rocker arm 2II exerts a pulling influence on the link 222 so that the arm I15 swings in the direction indicated by the arrow D (Fig. 11) thereby moving the carrier so that the ends of the fingers are finally directed toward the shock former, as shown in Figs. 5, 9 and 10. During these movements of the carrier, the lever I92 has shifted so that the stud 200 is located in the offset portion 203 of the slot MI. The sheaf is now in position to be empaled upon the tines of the shock former. This is effected upon actuation of the packer I53. The packer is being operated simultaneously with operation of the carrier, through rotation of the crankshaft I54. Upon rotation of the crank-shaft, the throw thereof moves the forked terminals I6I and I62 through the spaces between the fingers of the carrier so that the sheaf is engaged in the crotches thereof. Since the levers I63 are anchored to the links I64, the fork-like terminals have a reciprocatory or pitching motion with respect to the shock former so that upon release of the carrier, the sheaf gripped by the packer is moved into empaling relation with the tines and sloped in accordance with the position of the arms 62. The fingers of the carrier retain their grip on the sheaf until the sheaf has been engaged by the packer and moved to such a position that it will be stopped by the shock former. This is readily effected through the yielding action of the spring fingers I93. However, at this point the carrier begins its return movement by reason of return of the crank-arm 3I3 to its original position through the link 3I4. During movement of the bundle carrier toward the shock former, the arm 3" that is connected with the crank-shaft 2I3 passes the head 260", but on the return movement the arm 3I1 engages the head to move the lug 21I on the lever arm out of stopping engagement with the lug 263. The lug 263, however, will retain its position since it is engaged by the lug on the arm 262. Thus the movement of the lever arm 268 will have no effect on the clutch 254 at this time. The control lever I92 then shifts so that the stop shoulder 204 thereof engages the stud 200. The terminal arms 2I5 and 220 of the rocker arm 2 are now moving in reverse direction to that above described, so that a pushing influence is exerted by the link 222 and a pulling force by the rod 2I8. Stopped engagement of the control link I92 and the cooperating link 209 with the respective studs of the bracket now cause shifting of the levers I and arm I81--I88 so that the fingers I93 and I93 of the carrier move to open position and remain in open position when the carrier reaches its original position in alignment'with the discharge of the binder, ready to receive the succeeding sheaf.

After deposit of the sheaf on the tines of the shock former, the arm 51 on the upper end of the shaft 58 actuates the link 55 to swing the pawl 54 into engagement with the teeth 55 of the flange 50 thereby rotating the tube 49 in the collar 45 and advancing the shock former one space in the direction of the arrow (Fig. 9). As the arm 51 continues its movement, the link 55 is moved retractively to carry the pawl 54 over the teeth 55. The formed sheaves are successively deposited upon the shock former in juxtaposed contact until the first deposited sheaf engages the trip finger 294 just after deposit of the last sheaf on the shock former. The shock former is now completely packed and movement of the finger 294 effects actuation of the rod 299.

Since the bell-crank 241 has been moved out of the path of the lugs 252 and retained out'of this position by the cam on the crank-arm 3|3, movement of the rod 299 causes a rocking movement of the shaft and arm 265 to rock the bell-crank 25 through the link 265, whereby the arm 262 thereof is moved out of contact with the lug 263. If at this time the bundle carrier has completely effected deposit of the last shock and has started its return movement to receiving position, the lug 21! has also moved out of engagement with the lug 263 so that the clutch 254 is freed. The trip clutch is effective in rotating the shaft 2M1 through the driven connection thereof with the driving element of the other trip clutch 2M. Consequently the shaft 25 now rotates so that the crank 88 reciprocates the pitman 85, thereby actuating the rocker arms 83 and E2 to raise the tube 49 of the shock former. This movement of the shock former collapses the arms 52 so that the tines are retracted through the openings It! and I93 as shown in Fig. 5, freeing the shock so that it settles to the ground. Simultaneously the link l5l, through the arm l5fi, rocks the shaft M9 to open the gates H5 and HE, as shown in Fig. 10, so that the shock is cleared of the parts of the shock former. Upon opening of the gates the arm I is actuated to stabilize the shock as it slips to the ground. As the crank 88 continues its rotation the rocker arms Hand 12 are returned to their normal position restoring the shock former and closing the gates to reverse actuation of the respective levers.

It is thus obvious that I have provided a shocker wherein a shock is formed progressively with formation of the sheaves and that the shock is carried thereby until completely formed, after which it is automatically deposited on the ground. I find that the shock when thus formed is sufiiciently strong to retain its shape and sheds moisture so that the grain is thoroughly-protected while remaining in the shock.

There may be times when the operator may desire to clear a partially formed shock from the shock former. This may be effected by operating the lever 352 which oscillates the shaft 308 and hook 3H3, thereby rocking the arm 30!) and accomplishing the same result as effected upon automatic engagement of a shock with the finger 294.

From the foregoing it is obvious that I have provided a shocker that is of simple construction and capable of positive operation under timing control of the sheaf forming mechanism of the binder.
